How Long Renovations Really Take in Ottawa
In Ottawa, a bathroom renovation typically runs 2–7 weeks on site, a kitchen 3–14 weeks, a finished basement 6–16 weeks, and a home addition or full-home renovation 12–40 weeks. Permit review, custom-order lead times and structural work push projects toward the higher end of each range.
How long renovations really take in Ottawa.
Two kitchens that look alike can finish weeks apart depending on custom lead times, permit review and what we find once the walls are open, so every figure here is a range. The table below gives realistic on-site week ranges by project type, with the phases inside each.
Design, selections and permitting all happen before the on-site clock starts, so the earlier you settle your finishes, the closer you land to the low end of each range.
Typical Ottawa on-site duration.
| Project type | Typical on-site duration | Main phases |
|---|---|---|
| Bathroom renovation | 2–7 weeks | Demo → rough plumbing/electrical → waterproofing → tile → fixtures & finish |
| Kitchen renovation | 3–14 weeks | Demo → rough-ins & any wall changes → drywall & paint → cabinets → counters → appliances & finish |
| Basement finishing | 6–16 weeks | Framing → rough-ins → insulation & inspection → drywall → flooring → trim & finish (add time for a bathroom or egress) |
| Home addition / full-home renovation | 12–40 weeks | Foundation & structure → framing & roof → mechanical rough-ins → insulation → drywall → interior finishes |
On-site week ranges only, no costs. These are the same ranges our estimators use; your project could land anywhere in the range based on scope, permits and lead times.
What happens before the crew arrives.
The week ranges above cover construction only. Before them comes pre-construction, which varies widely: design and drawings, product selections, a fixed-price contract and, for permit work, City of Ottawa review through MyServiceOttawa. Larger projects that need structural review or a Committee of Adjustment variance add the most time here. The part you control most is locking in selections and getting drawings permit-ready early.
Why projects run toward the high end.
- Permit review timing, especially for additions, structural changes or variances
- Long lead times on custom cabinetry, special-order tile, windows or fixtures
- Hidden conditions found once walls, floors or ceilings open up
- Late or changed decisions on finishes and layout mid-build
- Structural or foundation work, underpinning, or moving load-bearing walls
